Doh!!! I knocked over a glass of pepsi, which landed on top of my amp, and neatly emptied it's contents into the vent on the top. Rats. It wasn't switched on, and I haven't turned it on. It's a SS Carlsboro PA mixer head. How should I go about testing this, to make sure everything is ok? I intend to give the amp a coupla days to dry out, then i'll open it up and clean off an residue. thx... doh!
